We recently had DirecTV installed in our home: one HD DVR in our family room (Model HR23-HD) and a regular definition DVR in our bedroom (MOdel R15??).  Does anyone know how we can access recordings on our bedroom DVR that we have set-up our family room DVR to record?  In other words, how can we synchronize our DVRs to "speak" with each other or have "shared memory"?

Thanks a lot!
